Answer:

Option B

3.75\ in^2

Step-by-step explanation:

we know that

The surface area of the front side is equal to the area of a square face of the cube plus the area of a right triangle of the triangular prism

so

SA=(1.5)^2+\frac{1}{2}(3.5-1.5)(1.5)

SA=2.25+1.50=3.75\ in^2

Question 9 (3 points)
Mila [183]

From the dot plot, we have that 90.91% of the students have 5 or more vowels in their first and last  names.

---------------------

The dot plot states that:

  • 2 students have 4 vowels in their first and last name.
  • 3 students have 5 vowels.
  • 8 students have 6 vowels.
  • 9 students have 7 vowels.

Then:

  • Total of 2 + 3 + 8 + 9 = 22 students.
  • 3 + 8 + 9 = 20 have or more vowels.

p = \frac{20}{22} \times 100\% = 90.91\%

90.91% of the students have 5 or more vowels in their first and last  names.

Solve for z a(t+z)=45z+67
ladessa [460]
Solve for z a(t+z)=45z+67
1. Expand
at+az=45z+67

2. Subtract at from both sides
az=45z+67-at

3. Subtract 45z from both sides
az-45z=67-at

4. Factor out the common term z
z(a-45)=67-at

5. Divide both sides by a - 45
z= \frac{67-at}{ya-45}

Answer: 
z= \frac{67-at}{a-45}

Tina is playing a computer game. She starts with 100 points, and she loses points based on the following rules: • Each time a pl
Natasha_Volkova [10]

Answer: she must complete 4 levels to have a point fewer than 20

Step-by-step explanation:

Given the following :

Starting point = 100 points

Passing a level = - 8 points

Catching a flower = - 3 points

Suppose Tina catches 6 flowers per level

Number of levels she must complete to have fewer Than 20 points

Total number of points lost per level:

Catching 6 flowers = -(6 × 3)

Passing the level = - 8

= - 18 + - 8 = - 26 points

Number of levels she must complete to have < 20

Let number of levels = y

Starting points - (26 × number of levels) < 20

100 - (26y) < 20

100 - 26y < 20

-26y < 20 - 100

-26y < - 80

y > 80/26

y > 3.07

Hence she must complete 4 levels to have a point fewer than 20

The "normal" high temperature for a June day in Albemarle is $82^\circ$ (degrees Fahrenheit). Last year, the first ten days of J
crimeas [40]

Answer:

6° F

Step-by-step explanation:

To get average of 10 days highs, we need to add all and divide by 10.

Average = \frac{84+88+91+92+96+94+89+78+87+81}{10}\\=\frac{880}{10}\\=88

And, the normal high temp is given as 82.

<em>How much higher is 88 than 82??</em>

<em />

It is 88 - 82 = 6°F above
